NAlLlNG-MACHINE.

SPECIFICATION forming ,part ofLetters Patent No. 288,425 dated November 13, 188

Application filed September-1 1, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, LOUIS GODDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in NailingMachines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention in nailing-machines, more cs pecially designed for boot and shoe work, has for its object improvements in the mechanical devices for selecting the nails and placing them separately. in the line of the descent of the driver. I

My improvements are herein illustrated as applicable to a machine such as represented in United States Letters Patent No. 265,227, granted to me September 26, 1882, to which reference may be had, but may, it is Obvious, be applied to other nailingmachines.

Figure 1 in side elevation represents portions of a boot and shoe nailing machine such as described in the said patent, but with my present improvements added. Fig. 2 is a broken detailof parts only of Fig. 1, viewing it from the right, a part of the nose and driverbar being broken out to show the transferrer and chute-cover beyond it. Fig. 3 is a broken detail taken from the left-hand side of Fig. 1, omitting the nail-feeding drum and all the chute except a small portion thereof at one end, just about enough to support one or two nails, the said figure showing most of the devices broken away from Fig. 2, some of the 3 5 parts shown in Fig. 2 being fully broken out from Fig. 3. Fig. 4 is a vertical nearly central section of Fig. 3, the chute being entirely omitted. Fig. 5 is an end view of the chute; Fig. 6, a side view of the delivery end of the chute, and Fig. 7 an. inner side view of the nose next the end of the chute.

The drum E, the chute 112., its cover or, vibrating head B, nail-driver bar a, nose 0, connection h between the nose and cover, the stop-rods f y, toothed sector f sleeve f spring-pressed pin 1, and shaft Care the same in construction and operation as those represented by the like letters of reference in the patent referred to. The head B has two like studs or rock-shafts, a (4, provided, respect 5o (1 against, respectively, the two acting camfaces 0 e of the cam-hub 6 fast on shaft 0. In practice one of the levers d (1 will be held by one of the said stop-pins f or f, to cause the transferrer carried by it to close the end of the roadway next to it, while the other lever or its roller-studis acted upon by the cam e or e, to cause the transferrer carried by that lever to alternately open and close the end of the roadway with which it co-operates, transferring one nail after another from the roadway into the nose or its passage r. These levers cl cl, for moving the separators, and the rockinglevers n a, the hollow hubs of which are slipped loosely, respectively, over the shafts a a referred to, are all substantially as in my 75.

application, Case A, No. 106,132, filed September 11, 1888.

The levers a n are provided, respectively, with anti-friction rollers k is, which are nor mally kept pressed against the cam-surfaces h h of the cam-hub e by the connecting-spring W.

The levers n a are provided, respectively, with separators o 0, (the one 0, Fig. 3, being best shown,) which operate in like manner in connection with a roadway of the chute, each 8 5 effecting the separation of nails singly from the ends of the roadways and delivering them tothe transferrers, as in my said application. Only the roadway marked 2 is shown in Figs.

2 and 3. These separators enter between the endmost nail and the one next to it, closing the raceway and chute, while the transferrer removes a nail from the end of the roadway of the chute into position substantially at the center line of the nose in line with the driverpassage r.

The face of the end of the chute m is shown- 111 Fig. 5, its side in Fig. 6.

The open ends of the roadways are inclined or made V-shaped with relation to each other, thereby causing the points of the nails to be carrled in toward the line of the driver-pas sage in the nose, and to keep the nails from falling down or hanging straight by gravity, I have provided the inner side of the nose (see Fig. 7) with two nail-rests, p p, the inner faces, 15, of which are set at the same inclination as the delivery ends of the roadways, so that the separators crowd the nails, one at a time, from the roadways and leave them lying on the said rests.

Each nail-rest p p is connected with astem, q, extended transversely through the nose and notched at its outer end for the reception of one end of a suitable spring, .9, (see Figs. 1 and 2,) shown as a forked steel plate fastened to the outer side of the nosec'by a screw, 8', the said spring acting to keep the nail-supports 1) p pressed against the end of the chute, the face 15- of each support 19 being in line with the wall of the roadway of the chute and filling the small space between the end of the chute and the side of the nose, and the nail removed from the roadway of the chute is supported, as stated, upon the face 15 of the rest.

The end of the rest next the end of the chute is slightly bevel'ed for the entrance between it the other transferrer and its separator to work,

and keeping the opposing separator and transferrer inactive.

I claim The chute and the nose provided with the driver-passage, and the spring-held nail-supporter placed in the nose and pressed toward the end of the chute and adapted to receive a nail upon it, combined with a transferrer to move the said nail into the line of the driverpassage, the supporter being at such time moved backward, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS GODDU.
